Imagine being able to capture HDR in a single RAW capture. With the A7S it’s not that far-fetched.
Here’s the -2 stop exposure with the shadows opened and clarity added in Lightroom 5.5:Sony A7S | FE 24-70mm F4 ZA OSS at 28mm | 1/1600 | F5.6 | ISO 100 (adjusted in Lightroom 5.5)

Images of the same scene in Rio de Janeiro shot on Sony A7R and A7S were processed in Adobe Lightroom 5.5 (Amazon | B&H) and adjusted for maximum dynamic range. Highlights were pulled down to -100 and Shadows were opened up +100

With mid-tones equal, the A7S image appears to hold an extra 1/2 stop of detail in both highlights and shadows – resulting in more shadow detail in the leaves of the trees without clipping highlights on the beach where the sand and water meet.

Since the images adjusted for maximum dynamic range appear flatter than I like, I’d add contrast, midtone clarity and a bit of vibrance (saturation) to put the snap back.
